Programming/Writing Code

I'm trying to write the code/ program for my Robot, I'm using a Raspberry pi 3 with an Adafruit stepper motor hat. I would like to use the Blynk app on my phone to operated my Robots motor with one of the Joystick Widgets. There are 2 motors and I have a Samsung galaxy S7 phone/ Android 7.0 operating system, For now I'd simply like to control the 2 DC motors with the joystick widget. I already have the Blynk Library installed on the Robot, I'm not sure what else the programmed may need but below I've listed the important items they will need to know. • Robot Info • Material: Aluminum alloy • Battery type: AAA battery • Color: Silver • Size: 220x140x80mm • Voltage: DC 12V Robot motors • Motor: 100 rpm • Blynk • [login to view URL] • Blynk library • [login to view URL] • Raspberry pi 3/Microcontroller. • Adafruit DC & Stepper Motor HAT for Raspberry Pi 2-B B+/A+ Robot Shield PWM • Controlled by a Samsung galaxy S7 android phone/ Android 7.0 operating system. • Python Blynk Library Command sudo apt-get install git-core git clone [login to view URL] ls cd blynk-library/linux make clean all target=raspberry ./[login to view URL] raspberry
